FIELD: engines and pumps.
SUBSTANCE: invention relates to thermal rotary pumps. Claimed engine comprises housing with channels, rotor, support and extending device (ED). Rotor is composed of the wheel with spokes. Said spokes have channels to guide n pairs of different-purpose vanes, where n = 2, 4…. Recesses making the combustion chambers are arranged between vanes of every pair. Rotor shaft consists of two parts rigidly secured at rotor ends. One of rotor shaft parts is hollow with support rigidly secured at its flange. ED parts are arranged at said support. ED comprises cranks, con rods and rocker. Rocker is tightly fitted on ED free running shaft. ED shaft is fitted in said rotor and incorporates levers with pushers. Spokes with guide channels are arranged tangentially relative to rotor shaft. Pusher of ED shaft every lever is articulated by rods with vanes of every pair. Compression vane is arranged inside combustion chamber. Said vanes have locking teeth and grooves for teeth of adjacent vane and retainer tips. Retainer comprises two-arm levers with retainers and cam. The latter is arranged on the housing inner side.
EFFECT: simplified design, higher reliability and efficiency.
